Example: adding an additional interface to a Single Firewall element
An example of adding an interface to a Single Firewall.
In the previous example, the administrator initially configured the firewall at the company’s new branch office with just two interfaces. Now the administrator decides to add a physically separated DMZ network for access to/from that office’s mail server to properly control both internal and external traffic with this publicly exposed server. The administrator:
- Creates an interface for the DMZ and gives it the following properties:
- Interface ID: 2
- IP Address: 192.168.2.1.
- Creates new rules in the firewall’s policy to allow traffic to/from the DMZ and NAT rules to translate between the private and public IP address of the mail server.
- Connects the new DMZ router to the firewall.
- Installs a Firewall Policy using the Management Client to transfer the new working configuration to the Firewall.
